Why Cost of bugs at different stages in Testing Fundamentals? - Purpose & Use Cases

The Big Idea

What if fixing a tiny bug early could save thousands of dollars later?

The Scenario

Imagine you find a mistake in a recipe only after baking a whole cake and serving it to guests.

Fixing it then means wasting ingredients, time, and disappointing people.

The Problem

Checking for mistakes only at the end is slow and costly.

It's easy to miss errors early on, and fixing them later takes much more effort and money.

The Solution

Understanding the cost of bugs at different stages helps us catch problems early.

This saves time, money, and keeps users happy by fixing issues before they grow.

Before vs After

✗ Before

Fix bug after release: expensive and slow

✓ After

Test early and often: cheaper and faster fixes

What It Enables

It enables teams to save resources and deliver better software by prioritizing early testing.

Real Life Example

A company finds a bug during design, fixes it quickly, and avoids costly recalls after product launch.

Key Takeaways

Finding bugs early reduces fixing costs.

Late bug fixes waste time and money.

Testing at every stage improves quality and saves resources.
